- Construction Management
S. T. Hudson provides mechanical design services that are necessary for marine and in-shore design projects. We design mechanical systems for a wide range of commercial enterprises, including cargo and vessel transfer, heavy piping, pollution control, chemical and petroleum terminals, refineries, and industrial and manufacturing facilities.
Our knowledgeable group of engineers have decades of experience in operations, maintenance, capital improvements, turnarounds, and other construction planning issues. We pull from this extensive knowledge base and work on behalf of our clients to ensure that our planning, design, and construction efforts will result in successful projects.
To stay on track and ensure we deliver consistent results, we utilize a step-by-step process for mechanical engineering projects.
Whether we’re evaluating the restarting of old plants and facilities, investing in new or existing plants, upgrading and modernizing old processes, increasing the capacity of existing facilities, or extending a facility’s lifespan, we offer innovative and practical solutions to any problems encountered.
As the first step in a project, the purpose of the conceptual design phase is to determine high level parameters such as purpose, production, place, and price—accounting for around 50% of the total cost.
A complete FEED (Front End Engineering and Design) package will prove the feasibility and the cost estimate from the concept design. With this, we address all of the client’s project requirements, which will ideally minimize the need for changes in subsequent stages of the design.
During this phase, the budget, design details, and all project plans and specifications will be completed to be approved for construction. This is the last chance to make any significant changes to the design.
Project management involves planning, implementing, monitoring, controlling, and closing out a project to meet measurable criteria detailed by the scope, schedule, budget, and plans for the project. We utilize tools such as cost tracking and cost control, scheduling, estimating, and risk analysis to steer the project to success.
We keep the project budget under control by adhering to and monitoring the project plan, project scope, estimate, and schedule. To avoid surpassing the project budget, we adopt a strict change management process when we identify and track variances.
Scheduling transforms the project plan into a manageable set of steps. We set deadlines and allocate resources, regularly reviewing and revising the plan as needed while it is in execution. The schedule continues to evolve as the project progresses, as variations develop, and risks are identified, handled, or eliminated.
From the conceptual to final phase, our estimating follows the American Association of Cost Engineers (AACE) recommended practices. We utilize advanced estimating systems such as Aspen Capital Cost Estimator (aka Icarus Kbase). We also validate and independently evaluate estimates, re-casting for project ranking criteria, as well as conduct a project risk analysis and contingency review.
Utilizing a complete piping design and analysis software package, we can provide a conceptual understanding of the entire piping and component system. This will enable the calculation of how the system operates, including pressures, ﬂow rates, and net positive suction head available.
Stress analysis is performed to verify that a piping system is routed and supported properly. The analysis determines movements and loads throughout the system from which the stresses in the piping material are calculated and checked for compliance to applicable codes.
We design marine vapor control systems to safely and efficiently destroy explosive vapors from marine cargo vessels during hydrocarbon loading activities. We can also certify that new or existing systems meet all state and federal regulatory requirements for the control of VOC emissions.
We document existing conditions to propose a change and create the initial design with laser scanning. This allows all the designers to see the actual conditions of the selected site and design within the scan instead of having to make repeated trips to the field.
With S. T. Hudson’s advanced Laser Scanning and 3D Modeling services, you can quickly capture precise 3D documentation of the existing facility with accurate measurements to assist in the planning phases for alterations and expansions of your equipment and structures, helping to reduce time in the field. Laser Scanning technology makes as built data collection simple, precise, accurate, and cost-effective.
Our data collaboration process gives you clear, detailed insights into the information we collect, with a user-friendly online system that makes it easy for you to access data. By having a more complete picture of your project, you’ll be able to make more accurate decisions.
We take care of data collection and processing in-house, which means we won’t have to bring in additional contractors—ensuring a quality process from start to finish.
Our Laser Scanning and 3D Modeling can advance your engineering projects in various ways. With Laser Scanning and 3D Modeling, you will get:
We have engaged S.T. Hudson’s services for the dredging of ferry slips, dredge disposal, design of fenders, pile clusters, and monopiles. S.T. Hudson also provides annual inspections of all marine facilities. I have found their engineers’ technical expertise to be above average to exceptional. Most recently, they added value to our projects through upper management’s subject matter expertise and regional connections with environmental officials to resolve problems.
